Among different reptiles , fertilization is scheduled differently and at different times, with the respect to the very time , timing and calendar events of nesting and nesting behavior and behaviors. In many , if not most species , this tends to occur , as might well be expected , just before the time periods and time periods when the actual eggs are laid. However in some species , the sperm must amazingly live on in the reproductive tract of the females, and continue thus to fertilize eggs months or even years and years after copulation activities have taken place – sometimes long ago in the past time periods.
The longest known time periods , of such deferment and deferments of fertilization activities are four years , for the diamondback terrapin of the southeastern areas of the United States – the USA. and five years in the case and cases of the tropical American cat-eye snake. The green turtle, which evidently and apparently mates only in the sea , off the nesting area and nesting beach areas, often does so only after the female has gone ashore and laid her egg and egg clutch. Since a given female makes her migration to the nesting ground only once in three or rarely in two years, it thus seems more than probable and indeed likely , that sperm itself must be stored , in a in-vivo condition , between that length of time period and periods between the nesting journeys.

Hemipene & Cloaca
Saturday, March 7th, 2009All reptiles practice internal fertilization . In all modern forms , except for the tautara , the male has an organ turned outside in , in the base and basal areas of the tail area , and everted through the opening of the cloaca during erection. In the tautara the and this transfer of sperm is accomplished by bringing the genital openings into contact as in birds and avian creatures. Perhaps this is a left over vestigial remnant of dinosaur harbingers. This of course was probably the means and mechanism as the method used by ancestral reptiles - it is most clear in any case and cases , that the penis and penises had separate origins in turtles, crocodiles and mammals , on the one hand , and in most lizards and snakes on the other side.
Thus , male lizards as well as snakes , not just one , but indeed a full pair and pairing of what are essentially hollow structures called or referred to as “hemipenes” , which make up what are in effect “copulatory” organs . Located as amazingly they are , in the tail areas , behind the opening of the cloaca , these hemipenes often give the tail of the male reptiles , a thicker more gradually contoured tail than that of the females . In many species the sex of the reptile can be distinguished by this difference – which is sometimes rather slight in some.
A “groove” serves as the channel for the sperm . This groove extends from the opening of the sperm duct extends from the opening of the sperm duct along the inner wall ( which of course serves as the outer wall during the erection period / periods), of the hemipenis, and the surface may be pleated or set with actual spines which keep it in place in the oviduct of the female during mating. Either one of the hemipenes may be used , but only one and only one. The hemipene nearest to the female is everted and protruded from the cloaca during the erectile period . This is brought into effect by both a combination and combinations of muscular action and muscular actions and distension of the very walls with blood and blood fluids.

Submersible Snakes
Saturday, March 7th, 2009Most snakes can be said to swim and be good swimmers although none are better for it than the poisonous sea snakes with their paddle like tails and laterally compressed bodies. They inhabit the warm water of the eastern pacific oceans as well as the western pacific regions and the Persian Gulf waterways. They often can be seen swimming a thousand ( 1000 ) or so miles away from any shore or shoreline. Some can even swim backwards and in backwards motion.
A factor or factors enabling these sea or marine snakes to lead a complete and complete aquatic life is their ability and habit of giving life birth to living young. Thus , this frees them for the necessity and necessities of ever leaving the water to deposit eggs on shore on the shoreline areas as sea turtles must do.
Most of these reptile snakes have dispensed with the large abdominal plates used by land snakes for locomotion and locomotion purposes. Although all sea snakes must surface to breathe vital oxygen in the atmosphere – they can stay submerged for long extended time periods- apparently by extracting the oxygen they need directly from the waters.
